1985 GT - Test your mustang knowledge, guess how fast i'll run 1/4 mile

[06_GT_Hawaii]

Aloha... I think that if you leave your gears at 3.73's - you're not going to be taking full advantage of your other mods.

You should really consider 4.11's. 4.56's might be too deep. But the 4.11's will help get you closer to where you want.

JMHO... Mahalo

I agree, i bought this thing with the mods it has now and i'm probably going to be "fine tuning" this thing. In other words undoing all the half arsed mods that have been done to it. When i first got it, it had lowering springs with KYB struts and shocks and I think someone wanted to use it as a daily driver. The heater core is no longer hooked up, the A/C is gone, the wiring for the MSD and other accessories are horrible, most of the gauges don't work, the ones that do are inaccurate probably because of a ground issue (turn on lights the gauges change values). So i have my work cut out for me, not a big deal though as long as i focus on one thing at a time. Since it has 3.73 gears my 26" diameter slicks should work fine although, i agree it does need more gear. I was hoping to see the mph in the 1/4 with the nitrous on and change gear from there.
I'm a glutton for punishment so i guess this GT is a perfect match for me.

Sorry i missed your post the first time through and just now read it. Sorry i didn't reply, now i feel bad. What i would do (you probably figured it out) would be to loosen the mount bolt, take a jack with a block of wood and jack up that side of the engine.
Yeah, send me some contact information (email or phone # and i'll contact you before i head out.) It's really fun and doesn't cost that much (compared to other stuff you can do all day). There's usually a few mustang guys there at the track and they are more than happy to b.s. and help out when you need it. I should be heading out there soon.

I think around a 13 flat all motor, low 12's with the funny gas. Your track is almost at sea level I think thats what is throwing people off. Around here you will be lucky to get mid to high 13's. Albuquerque NM (5400ft)

Okay you win tireburner163. You know what you're talking about and your 1000's of posts aren't stupid... I'm but an amateur with a measily 370 posts and need to have things explained to me, by you, my hero and demigod. Let's hold hands, sing Kumbaya

Can we move on now?

Dude... you're way off base here, and you're digging yourself a hole. You're certainly entitled to your opinion, but you don't have much of a chance of legitimately debating this.

GT-40P heads are VERY good heads if you're not trying to get your weekend warrior above 110mph or run mid 12's in the quarter. They respond very well to a port job, and the flow more than enough to be matched up to a nice low lift aftermarket cam. As everybody has pointed out, the F-303 cam (which is the best of the alphabet cams in general) probably has too much lift for the GT-40P heads to truly use at maximum efficiency (GT40-P heads actually drop a little flow between .500 and .550 lift from the factory), but that doesn't negate the fact they are far better than stock.

I don't know what you have/haven't seen, and I don't care. There are people on this site that have put E7 headed cars into the 12's without any forced induction or nitrous. There are witnesses to stock fox bodies running high 13's right off the factory floor with bumped timing (not that more than a very few can duplicate that)

Good driving can mean more than a lot of boltons, but eventually, even an average driver with enough go-fast parts will be faster than a great driver with no go fast goodies.

Posts don't mean much to me these days, but I have been a member of this site since 1999, which is a lot longer than most here can say. Even though I don't know as much about the latest Mustang parts available or even necessarily as much as I did when I was an active member, I do still have more than enough knowledge to spot the correct assumptions in this debate.

I like how you start your "can we just move on" thread with a few jabs... yeah, that always works, lol.

Oh, and btw, Jeff Chambers was running 10's on a N/A unported GT-40P headed car, if I remember right.

Dude quit trying to start crap. Let's relax.

[Unit 5302]

I'm more than relaxed. If you think that was me trying to start crap, then you really don't know me very well, which is surprising considering how long we've been registered here.

If I meant to insult you, you'd know it.

guys you spend to much time and too much writing to try to get to me. It's all opinion, and jeez it's the internet... don't get mistaken for e-thugz!!! Chill out! Life's short

[RBatson]

I was going to guess mid 13s but... you already ran 13.30s? Hmm.. you have since removed the a/c? Honestly, I thought low 13s was the best you would see but if you have already seen 13.3 then I'm going to have to guess a 13 flat. I think you are a much better driver than you give yourself credit.

As far as guessing at times with bolt ons, I believe Bob Cosby was running high 11s with a bolt-on 98 cobra. If your looking for a drag slip hero... there you go. I don't think I could pull that off.

[nitrousboy]

i would say 13.00 with out the bottle on a good day with the bottle 12.50 ish.

I think nitrous is going to add a lot more than 1/2 a second. My old car ran 13.5's on motor and 12.1 on a 150 shot. My coupe ran high 12's on motor and 11.60's on a 150 hp shot.

I used to go a few times a year. The first time I went you probably weren't too far out of diapers. I do have a good friend that ran Pro 5.0 though and it seems to me he said the cars should have 4 cyl springs all around. Any other questions? I'm about to get the 89 running again.. I guess you might wanna run it.

So what your saying is that you USED to go a couple times a year.......but now you don't. So basicly you spend little time at the drag strip. Just because I didn't even have a drivers license when you first started drag racing, doesn't mean you know any more than me. Times change, GT-40 intakes and E-303 cams used to be the shit.........not anymore.

Who was your buddy that ran Pro 5.0?

I'm just going buy what a few people say about how to set up a suspension. I mean really...what do a couple of people like David Wolfe know about suspension stuff anyway.

Glad do see your getting the 89 running again.

I'd be glad to run you, I'm always up for a little fun.

I know things change quickly when it comes to racing. Actually I USED to go quite a bit. Life changes and so does interests.. I changed job description, got a new car and got into the stock market and so on.. I'm not saying I know anymore than you, I'm not a mechanic and never really got deep into an engine but.. 4 cyl springs on the back is almost a given.

My friend was sponsered by Holcomb. He drove the car in their ad. I don't even know if they still use that picture but he is still working on mustangs.

Names don't really impress me much anymore. I thought I was being smart by ordering a chip off a well known guy by the name of Chris Johnson. The Diablo had just came out but I thought I would go ahead and get a custom chip by the legendary Chris Johnson. The chip never did work and he really didn't seem to care. Though he said he would look at it if I drove many hours out of my way for $75 an hour.

When I get it going again I'll let you know.

[tireburner163]

You got a chip from JMS and it didn't work? For the mach 1? If you would have called and talked to Monte he probably would have fixed it for you. JMS does all my tune work and does a good job of it as well. Doesn't really seem like them to be screwing people around?




But back to my main point.

Jump over to any place that has some REAL tech such as www.hardcore50.com or www.nmraracing.com and see what those guys are doing. Not what they THINK will work or what is SUPOSE to work, but what IS working in their race cars.

I did a V-8 conversion several years ago on a 92 LX. It was cutting 1.79 60 foots with 70/30's and otherwise stock 4 banger supension. I swaped in a set of 95 GT rear springs and added a rear-sway bar. The next week at the tack 60 foots dropped to a 1.71

The 4 banger rear springs don't work unless you are shocking the tires very hard. You want the front end to come up, but the rear-end to say level and plan the power. Not just waste all your launch energy.

Either 1) the springs will absorb a lot of your launch energy and/or 2) the springs are so soft that when you do hook, the car will unload about 30-40 feet out and spin.

Take a look at the spring rates on Eibach's drag launch kit. Much softer front springs and rear springs that are about the same as stock.

[andy669]

Every stock suspensioned drag racing Mustang I have been associated with has had stock V-8 springs in the rear. 4 cylinder springs up front are the most common for guys not using coil overs.

I hate to be redundant but.. No, not for the Mach. I said when the Diablo chip first came out which was in the spring of 2000, I think. I paid $302 for a chip to go in the 89 stroked and blown mustang, the one that currently needs main bearings. I actually met Chris in 1999, nice guy . I talked with him a couple times on the phone and we talked for quite a bit, great guy. I talked to him about upgrading my Vortech and ordering a chip. A few months later, when I was ready to order the chip I ended up talking to someone that sounded like they were eating their lunch, which I hate. Anyhow, when I got the spec sheet, which was supposed to list my mods, it said long tubes(which I don't have) and a few other minor things that I can't remember didn't match up. I called and they said it was no big deal, didn't speak to Chris. In the meantime I ended up having some cooling and charging problems that set me back a bit and by the time I got around to dealing with the chip again.. I called and told them the car was running way rich, I couldn't tune it and the chip wasn't doing anything. I asked if they could look at it in Bradenton and figure out why it wasn't working, they said they would be busy with their car at the spring break shootout, I can understand that. Then I asked if I could come by earlier in the week, on my way down to Bradenton, and Chris said he would but he got $75 an hour. I said I bought a chip that doesn't work, he said he doesn't work for free. The more I thought about it the madder I got. I'm not a rich man, I paid $302 for a chip and I expect it to do what it was supposed to do. It did absolutely nothing and I have no idea why. I don't think I should have to pay $75 an hour for someone to figure out why their product doesn't work.. maybe I caught him on a bad day, I don't know. I do know that I wish I had ordered the new Diablo chip instead of going with someone that impressed me. You have to remember, I first read about Chris Johnson and his little white coupe back around 1991(I believe), I was quite impressed that someone could get an extra 100hp out of tuning the ecm.

well i injured myself at work so the now almost done Gray GT may not run for awhile....crap.....things were going to good, lol

[fordmustang]

hi , i hope that you get 13.low , good luck
